11 DragonFly provides support for PCI-based TV cards using a Brooktree Bt848/849/878/879 or a Conexant CN-878/Fusion 878a Video Capture Chip with the [bktr(4)](http://leaf.dragonflybsd.org/cgi/web-man?command#bktr&section4) driver. You must also ensure the board comes with a supported tuner, consult the [bktr(4)](http://leaf.dragonflybsd.org/cgi/web-man?command=bktr&section=4) manual page for a list of supported tuners.\r

15 To use your card, you will need to load the [bktr(4)](http://leaf.dragonflybsd.org/cgi/web-man?command#bktr&section4) driver, this can be done by adding the following line to the `/boot/loader.conf` file like this:\r

43 Of course these messages can differ according to your hardware. However you should check if the tuner is correctly detected; it is still possible to override some of the detected parameters with [sysctl(8)](http://leaf.dragonflybsd.org/cgi/web-man?command#sysctl&section8) MIBs and kernel configuration file options. For example, if you want to force the tuner to a Philips SECAM tuner, you should add the following line to your kernel configuration file:\r

74 If you encounter any problem with your TV card, you should check at first if the video capture chip and the tuner are really supported by the [bktr(4)](http://leaf.dragonflybsd.org/cgi/web-man?command#bktr&section4) driver and if you used the right configuration options. For more support and various questions about your TV card you may want to contact and use the archives of the [DragonFly User related mailing list](http://leaf.dragonflybsd.org/mailarchive/).\r
